Data validation is a feature that allows you to set rules in cells to ensure that the data entered meets specific requirements. It helps users avoid input errors and improves the accuracy and consistency of data.

Currently, the following data validation types are supported:
- Number
- Integer
- Text length
- Date
- Checkbox
- Dropdown list (single/multiple selection)
- Custom formula

Complete Facade API type definitions can be found in the [FacadeAPI](https://reference.univer.ai/en-US).

### Add a data validation rule

[`univerAPI.newDataValidation()`](https://reference.univer.ai/en-US/classes/FUniver#newdatavalidation) can create a new data validation builder, which returns an `FDataValidationBuilder` instance that can generate data validation rules through chained calls.

Here are some member methods on [`FDataValidationBuilder`](https://reference.univer.ai/en-US/classes/FDataValidationBuilder):

| Method | Description |
| ------ | ----------- |
| build | Build the data validation rule. |
| requireCheckbox | Sets the data validation rule to require that the input is a boolean value; this value is rendered as a checkbox |
| requireDateAfter | Set the data validation type to DATE and configure the validation rules to be after a specific date |
| requireDateBefore | Set the data validation type to DATE and configure the validation rules to be before a specific date |
| requireDateBetween | Set the data validation type to DATE and configure the validation rules to be within a specific date range |
| requireDateEqualTo | Set the data validation type to DATE and configure the validation rules to be equal to a specific date |
| requireDateNotBetween | Set the data validation type to DATE and configure the validation rules to be not within a specific date range |
| requireDateOnOrAfter | Set the data validation type to DATE and configure the validation rules to be on or after a specific date |
| requireDateOnOrBefore | Set the data validation type to DATE and configure the validation rules to be on or before a specific date |
| requireFormulaSatisfied | Sets the data validation rule to require that the given formula evaluates to `true` |
| requireNumberBetween | Sets the data validation rule to require a number that falls between, or is either of, two specified numbers |
| requireNumberEqualTo | Sets the data validation rule to require a number equal to the given value |
| requireNumberGreaterThan | Sets the data validation rule to require a number greater than the given value |
| requireNumberGreaterThanOrEqualTo | Sets the data validation rule to require a number greater than or equal to the given value |
| requireNumberLessThan | Sets the data validation rule to require a number less than the given value |
| requireNumberLessThanOrEqualTo | Sets the data validation rule to require a number less than or equal to the given value |
| requireNumberNotBetween | Sets the data validation rule to require a number that does not fall between, and is neither of, two specified numbers |
| requireNumberNotEqualTo | Sets the data validation rule to require a number not equal to the given value |
| requireValueInList | Sets a data validation rule that requires the user to enter a value from a list of specific values |
| requireValueInRange | Sets a data validation rule that requires the user to enter a value within a specific range |
| setOptions | Sets the options for the data validation rule |

```typescript
const fWorkbook = univerAPI.getActiveWorkbook()
const fWorksheet = fWorkbook.getActiveSheet()

// Create a new data validation rule that requires a number between 1 and 10 fot the range A1:B10
const fRange = fWorksheet.getRange('A1:B10')
const rule = univerAPI.newDataValidation()
  .requireNumberBetween(1, 10)
  .setOptions({
    allowBlank: true,
    showErrorMessage: true,
    error: 'Please enter a number between 1 and 10',
  })
  .build()
fRange.setDataValidation(rule)
```

### Clear data validations of range

```typescript
const fWorkbook = univerAPI.getActiveWorkbook()
const fWorksheet = fWorkbook.getActiveSheet()

// Clear data validation of range A1:B10
const fRange = fWorksheet.getRange('A1:B10')
fRange.setDataValidation(null)
```

### Get data validations of Range / Worksheet

The returned data validation rule object is an `FDataValidation` instance, which can be used to obtain the conditions, options, etc. of the validation rule.

Here are some member methods on [`FDataValidation`](https://reference.univer.ai/en-US/classes/FDataValidation):

| Method | Description |
| ---- | ---- |
| getCriteriaType | Gets the data validation type of the rule |
| getCriteriaValues | Gets the values used for criteria evaluation |
| getHelpText | Gets the help text information, which is used to provide users with guidance and support |
| getRanges | Gets the ranges to which the data validation rule is applied |
| setCriteria | Set Criteria for the data validation rule |
| setOptions | Set the options for the data validation rule |
| setRanges | Set the ranges to the data validation rule |
| delete | Delete the data validation rule from the worksheet |

```typescript
const fWorkbook = univerAPI.getActiveWorkbook()
const fWorksheet = fWorkbook.getActiveSheet()

// Get all data validation rules in current sheet.
const rulesOfSheet = fWorksheet.getDataValidations()

const fRange = fWorksheet.getRange('A1:B10')

// Get first data validation rule in current range.
const ruleOfRange = fRange.getDataValidation()
console.log('ruleOfRange:', ruleOfRange, ruleOfRange?.getCriteriaValues())

// Get all data validation rules in current range.
const rulesOfRange = fRange.getDataValidations()
```

### Update/Delete data validation

```typescript
const fWorkbook = univerAPI.getActiveWorkbook()
const fWorksheet = fWorkbook.getActiveSheet()

// Create a new data validation rule that requires a number equal to 20 for the range A1:B10
const fRange = fWorksheet.getRange('A1:B10')
const rule = univerAPI.newDataValidation()
  .requireNumberEqualTo(20)
  .build()
fRange.setDataValidation(rule)

const newRuleRange = fWorksheet.getRange('C1:D10')

// Update the rule after 3 seconds
setTimeout(() => {
  fRange.getDataValidation()
    // Change the range to C1:D10
    .setRanges([newRuleRange])
    // Change the criteria to require a number between 1 and 10
    .setCriteria(
      univerAPI.Enum.DataValidationType.DECIMAL,
      [univerAPI.Enum.DataValidationOperator.BETWEEN, '1', '10'],
    )
    // Change option to stop input on validation errors and show error message
    .setOptions({
      allowBlank: true,
      showErrorMessage: true,
      error: 'Please enter a valid value',
      errorStyle: univerAPI.Enum.DataValidationErrorStyle.STOP,
    })
}, 3000)

// Delete the rule after 6 seconds
setTimeout(() => {
  newRuleRange.getDataValidation().delete()
}, 6000)
```

### Get validator status

```typescript
const fWorkbook = univerAPI.getActiveWorkbook()
const fWorksheet = fWorkbook.getActiveSheet()

// Get data validation validator status for current workbook.
fWorkbook.getValidatorStatus().then((status) => {
  console.log('===statusOfWorkbook', status)
})

// Get data validation validator status for current sheet.
fWorksheet.getValidatorStatusAsync().then((status) => {
})

// Get data validation validator status for current range.
const fRange = fWorksheet.getRange('A1:B10')
fRange.getValidatorStatus().then((status) => {
  console.log('===tatusOfRange', status)
})
```

### Event Listeners

Full event type definitions, please refer to [Events](https://reference.univer.ai/en-US/classes/FEventName).

The data validation module provides a series of events for monitoring validation rule additions, updates, deletions, and validation status changes. All events can be listened to using `univerAPI.addEvent()`.

#### Validation Rule Change Events

`univerAPI.Event.SheetDataValidationChanged`: Triggered after a validation rule changes

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.SheetDataValidationChanged, (params) => {
  const { origin, worksheet, workbook, changeType, oldRule, rule } = params
})

// Remove the event listener, use `disposable.dispose()`
```

`univerAPI.Event.BeforeSheetDataValidationAdd`: Triggered before adding a validation rule

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.BeforeSheetDataValidationAdd, (params) => {
  const { worksheet, workbook, rule } = params

  // Cancel the data validation rule addition operation
  params.cancel = true
})

// Remove the event listener, use `disposable.dispose()`
```

`univerAPI.Event.BeforeSheetDataValidationDelete`: Triggered before deleting a validation rule

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.BeforeSheetDataValidationDelete, (params) => {
  const { worksheet, workbook, ruleId, rule } = params

  // Cancel the data validation rule deletion operation
  params.cancel = true
})

// Remove the event listener, use `disposable.dispose()`
```

`univerAPI.Event.BeforeSheetDataValidationDeleteAll`: Triggered before deleting all validation rules

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.BeforeSheetDataValidationDeleteAll, (params) => {
  const { worksheet, workbook, rules } = params

  // Cancel the data validation rule deletion operation
  params.cancel = true
})

// Remove the event listener, use `disposable.dispose()`
```

#### Validation Rule Update Events

`univerAPI.Event.BeforeSheetDataValidationCriteriaUpdate`: Triggered before updating validation rule criteria

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.BeforeSheetDataValidationCriteriaUpdate, (params) => {
  const { worksheet, workbook, ruleId, rule, newCriteria } = params

  // Cancel the data validation rule criteria update operation
  params.cancel = true
})

// Remove the event listener, use `disposable.dispose()`
```

`univerAPI.Event.BeforeSheetDataValidationRangeUpdate`: Triggered before updating validation rule ranges

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.BeforeSheetDataValidationRangeUpdate, (params) => {
  const { worksheet, workbook, ruleId, rule, newRanges } = params

  // Cancel the data validation rule range update operation
  params.cancel = true
})

// Remove the event listener, use `disposable.dispose()`
```

`univerAPI.Event.BeforeSheetDataValidationOptionsUpdate`: Triggered before updating validation rule options

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.BeforeSheetDataValidationOptionsUpdate, (params) => {
  const { worksheet, workbook, ruleId, rule, newOptions } = params

  // Cancel the data validation rule options update operation
  params.cancel = true
})

// Remove the event listener, use `disposable.dispose()`
```

#### Validation Status Events

`univerAPI.Event.SheetDataValidatorStatusChanged`: Triggered when a cell's validation status changes

```typescript
const disposable = univerAPI.addEvent(univerAPI.Event.SheetDataValidatorStatusChanged, (params) => {
  const { worksheet, workbook, row, column, status, rule } = params
})

// Remove the event listener, use `disposable.dispose()`
```

Each event includes the following common parameters:
- `workbook`: Current workbook instance
- `worksheet`: Current worksheet instance

Special parameters:
- `rule`: The related validation rule object
- `ruleId`: Unique identifier of the validation rule
- `status`: Validation status (only in `SheetDataValidatorStatusChanged` event)
- `newCriteria`: New validation criteria (only in `BeforeSheetDataValidationCriteriaUpdate` event)
- `newRanges`: New validation ranges (only in `BeforeSheetDataValidationRangeUpdate` event)
- `newOptions`: New validation options (only in `BeforeSheetDataValidationOptionsUpdate` event)

All event callbacks with the `Before` prefix can use `params.cancel = true` to prevent the corresponding operation.

### Change List render mode

```typescript
dataValidation.setOptions({
  // support TEXT, ARROW, CUSTOM
  // default is `CUSTOM`
  renderMode: univerAPI.Enum.DataValidationRenderMode.TEXT,
})
```
